   *
   * This is useful when including files from parent directories (using `..` in the glob pattern),
   * as the default behavior strips `..` segments which can result in unexpected destination paths.
   *
   * @example
   * // In a monorepo with structure: apps/trigger, apps/shared
   * // From apps/trigger/trigger.config.ts:
   * additionalFiles({
   *   files: ["../shared/**"],
   *   destination: "apps/shared"

   * // Files from ../shared/utils.ts will be copied to apps/shared/utils.ts
